Application led4 January 18- 1906- Serial No. 296.701.

To all ijfhom it 'may concern:

Be it known that I. Enwix J. JE'NNEs's. a citizen of the L'nited States. residing at Chicago. in the county of Cook and State of Illinois. have invented new and' useful Improvements in Spring-Suspensionfor Automobiles and other Vehicles. of which the following is a full. clear. concise. and exact description, reference 'being had to the accompanying drawing, forming n part of this specification. v s

This invention relates to improvements in spring suspension for automobiles and other vehicles. and contemplates the use of simple and efii'cientmeans to prevent too great distention o the supporting spring of a vehicle body under load or extraordinary jars, and to aid in absorbing the shocks of travel. and to control the action of. the supporting spring to' restrain and delay its tendency to resume its normal position after a de-A pression thereof.

For a full description of the invention land the merits thereof. and also to acquire a knowledge of the details of construction' of the .means for effecting the results. reference is to be had to the following description and accompanying drawings. l v

Corresponding and like parts are referred to in th'e following description and indicated in the drawings by the same reference characters.

While the essential and characteristic features of the invention are susceptible of modification` still the preferred embodiment of the invention is illustrated in the accompanying drawings in which: I

Figure 1 is an elevation partlyin cross-section. showing the arrangementof the parts comprising the spring suspension; and. Fig. 2 is similar t'o Fig. l, showing a modification. i

Referring to the drawings. 1 designates a'n ordinary leaf spring 2 is a link pivotally connected both to one.

end of the leaf spring 1 and to a bracket 3 which is secured to the longitudinal side 4 of the under' frame of the automobile or other vehicle. Clips 5 secure the said leaf spring 1 to the integral lugs 6.v 6, ofthe transverse member 7 of the under frame. The rear of the longitudinal side 4 of the under flame is bent-'downward and from its end 9 a lever 8 is pivotally suspended at substantially its middle point.

Fig. 1 shows the lever in the form of the leaf spring 'struct-ure, while in Fig. 2 a rigid structure for the lever is shown. Oneend of the lever 8 is pivotally secured by suitable means to the end l0 of the leaf springl and the other end of the lever 8 is secured to a bolt-11 which in turn-is securedto a cross-head 13. Bolts or standards 14. 15 dependingvfrom the longitudinal side ot' the under frame 4 have secured thereto. the crosshead 12 and pass freely through openings 18, 19 in the cross-head 13;-An opening 17in the cross-head 12 permits a'ree movement of the bolt 11 therethrough. A coil spring 16 is secured bysuitable' means to the cross heads 12 and 13, and acts to normally press the head of the bolt l1 secured to cross head 13 against the underside'of the longitudinal side 4 of the under frame. It is obvious that the spring suspension herein set forth operates to prevent great distention of the leaf spring 1 under load, and serves to qabsorb shocksof travel and restrains and delays the tendency of the leaf spring 1-to resume its normal positioniaftr any depression thereof.

.Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

-witlx the opposite end of said supporting spring, a second spring secured to the vehicle, and means carried by the other ond of said lever and prtecting vertically upwards .to engage said second spring, whereby the downward movementof said other end of the lever is opposed by the action of saidsecond spring.

2. A spring-suspension for vehicles comprising, in c m hination, a supporting,r spring connected at lone end to he body of the vehicleand at an intermediate point connected to the running gear, a resilient lever pivoted at an intermediate ponl to the body of the vehicle and at one end connected with the opposite end of said supporting spring. a second spring secured to the vehicle, and means carried by lhe other end of said lever and projecting vertically upwards to engage said second spring. whereby the downward movement of said other end of the lever is opposed by the action of said second spring.

in witness whereof, I- -have hereunto subscribed my name in the presence of two witnesses.
